# OBD JScan vs V

The clearest difference is review sentiment: OBD JScan at 79% against V's 0%. OBD JScan also leads on rating (4.7 vs 4.0) and ratings volume (1.3K vs 2). V's advantage is update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. OBD JScan sells 7 one-off in-app purchases and V sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

OBD JScan holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: OBD JScan has 1.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 79% of OBD JScan's written reviews are positive against 0% of V's.

OBD JScan ships an update every 3 weeks, V weekly. The most recent releases landed on September 28, 2026 and September 10, 2026 respectively.
